Hey and congrats on the little one. Our house is two stories too, and yeah, the signal dropping was a constant headache at first, drove me nuts when I'd be downstairs and suddenly lose connection. What made a big difference was opting for something that uses a dedicated frequency instead of relying on home WiFi, because WiFi can get interfered with by all sorts of things like microwaves or thick walls. We positioned the parent unit near a window facing the nursery, which seemed to help the signal travel better between floors. And keeping other electronics away from it reduced any static. It's been smooth sailing since those tweaks, no more spotty coverage even when I'm in the basement doing laundry or whatever.

Yeah, Here is a quick focus test to separate calibration from optical issues. Set a book on a table at a slight angle, choose single point AF, and focus on a specific line of text near the middle at the widest aperture. Take several shots and review at high magnification to see where the sharpest plane landed. If it consistently sits in front or behind that line, use AF fine tune on the body to correct. Do the same scene using live view with magnified manual focus. If those frames are tack sharp, the optics are probably fine and it is a focus calibration problem. If nothing looks truly crisp even around f8 at different distances and that suggests an internal issue that needs a technician. Quick sanity check as well adjust the diopter so the viewfinder display looks perfectly sharp. Short but important.
